Passiflora is a very large genus of more than 400 tropical climbers, annuals, perennials, shrubs, and trees. They are grown mainly for their exotic flowers with prominent central stalks. Yellow fruits are edible when fully ripe and resemble small chicken eggs. The vast majority of Passiflora species are climbers, and they are excellent for growing on a wall or trellis. They use tendrils to grab their supports.
